The Establishment of Ecoregion BiologicalReference Sites for New Jersey Streams

INTRODUCTION

Background

Water quality monitoring by the States became a requirement following institution of the CleanWater Act of 1972. Initially, the emphasis by the U.S. Environmental Protection Agency was ontechnology based point-source pollution control (USEPA 1977, 1985). Assessments of pollutionabatement were largely made through "end-of-pipe" monitoring of physical-chemical parameters.Recently, however, the water quality-based approach to pollution assessment and control hasgained prominence with USEPA and the States. The water-quality based approach concentrateson how water pollution, and its remediation, are reflected by instream water quality. As such, theapproach requires varied types of data, both biological and chemical/physical.

Biosurvey data (monitoring of indigenous aquatic biota) are the best means for evaluating thehealth of instream aquatic life. If an impairment has been detected, additional chemical andtoxicological testing can be conducted to identify causative agents, to locate the source(s) of thatagent, and provide sufficient information for the formulation of a mitigation plan. Subsequent tomitigation, biosurveys can provide the investigator with an evaluation of the effectiveness of thecontrol measures implemented. While not intended to replace the other components of a waterquality monitoring program, the monitoring of aquatic biological communities is a much morecost-effective approach than chemical monitoring for screening instream water quality.

In New Jersey, "biomonitoring" programs were initiated in the mid-1970's by the Departmentof Environmental Protection, Division of Water Resources, in cooperation with the USEPA.From the existing Ambient Monitoring Network of the U.S. Geological Survey, a limitednumber of stations were adopted as routine biomonitoring sites, an important aspect of whichwas to establish baseline biological data for the state's waterways. This was supplemented bylocalized "intensive surveys" wherever priorities dictated. However, it was later found that dueto the effects of new development, either point sources or non-point pollution sources, or both,many of the original 31 "fixed stations" were either inaccessible or in a degraded condition.An updated reference station database for use in conducting either site-specific or watershed-based intensive surveys, robust enough to be used throughout the State for an extended periodof time, was needed. The Ecoregion concept, as promoted by USEPA, provided a likelyframework for creating just such a biomonitoring reference station database.

The Ecoregion Concept

Habitat quality becomes a major factor contributing to biosurvey results. Where stations arephysically comparable, detected impacts can be attributed to water quality factors. Conversely,habitat degradation (e.g. channelization, siltation, defoliation of surroundings, etc.) alone canaccount for biological impairment in a stream. Despite other sources of water quality degradation,variations in aquatic habitat can have a corresponding influence on biological communitystructure. The ecoregion concept assumes that waterbodies reflect the lands they drain and thatsimilar lands should produce similar waterbodies. USEPA's application of their concept recognizesthe innate differences that exist among geographical regions (e.g., forest/upland, agricultural,wetland, etc.). These regional differences have been delineated across the U.S. for the USEPAby Omernik (1987a) based on land-surface form, soil, potential natural vegetation, and land use.This approach is much more robust and ecologically relevant than maps generated from singlevariables, such as hydrologic conditions.

Indigenous stream habitats can thus be categorized according to their respective ecoregions.Biological communities, as components of the ecosystem, are expected to differ amongecoregions, but be similar within any given ecoregion. The ecoregion concept thus provides ageographic framework for the management of aquatic ecosystems. A major application of thisconcept is that several minimally-impacted sites within a region can serve as reference sites forthe assessment of stream water quality for the entire region (Plafkin et al, 1989).

The NJDEP Bureau of Water Monitoring (BWM) has, since its inception, performed manyoriginal biomonitoring studies throughout the waters of the State (NJDEP/BWM, Unpublishedreports). Reference stations in our surveys have, until recently, been utilized only on a watershedor site-specific basis. However, from 1989 through 1991 almost the entire State, including threemajor and four smaller ecoregions, was surveyed to find stream locations qualifying as ecoregionbiological reference sites. Data from this initial survey will serve as the baseline for each referencesite. As the opportunity arises, additional reference stations will be added based upon themonitoring results obtained from the Ambient Biomonitoring Network (AMNET).

The establishment of ecoregion sites will serve to complement current and future watershedbiomonitoring and trend assessments. It will, therefore, serve as a basis for the statewide waterquality inventory (305B) and planning/management decisions involving surface water qualitystandards and biocriteria.

NEW JERSEY ECOREGIONS

The USEPA ecoregions overlapping New Jersey from the surrounding states are shown by solidlines in Figures 1 and 2 (from Omernick [1987b]). New Jersey constitutes the northeasternboundaries of the Northern Piedmont and Middle Atlantic Coastal Plain (these two ecoregionscomprising at least 90% of the state's area), while smaller segments of the southern boundariesof four upland ecoregions overlap the northernmost portion of the state. We would propose,however, certain modifications to this scheme, giving greater detail and resolution within NewJersey (Figure 1).

Geologically, New Jersey is comprised of portions of four major, "Provinces," (in Wolfe, 1977).The provinces are (north to south) the Appalachian Ridge and Valley, Highlands, Piedmont, andAtlantic Coastal Plain. The boundary between the Piedmont and the Coastal Plain provinces isknown as the "Fall Line" (see Figure 1). The Fall Line delineates the hard consolidated andcrystalline substrates to the north, from the more easily eroded sedimentary materials of theCoastal Plain. Streams to the north of the Fall Line are largely swift-flowing with rocky bottoms,often incorporating falls and rapids. Streams to the south of the Fall Line are slower-flowing withtheir bottoms composed of finer sediments, often sandy.

By comparison, the USEPA ecoregion mapping divides New Jersey into six regions (MiddleAtlantic Coastal Plain, Northern Piedmont, Northeastern Coastal Zone, Northeastern Highlands,Northern Appalachian Plateau and Uplands, and the North Central Appalachians). The first twolisted above cover the majority of the State's land surface.

New Jersey Modifications to the USEPA Design

A reevaluation of USEPA's ecoregion plan (from Omernick, 1987) using the traditional geologicalprovinces and elevation above sea level as guides, suggests that three major ecoregions, ratherthan the two described by USEPA's ecoregion map, are in order. Essentially, New Jersey'smodification would divide the Northern Piedmont ecoregion in two, with the upland sectorencompassing most of New Jersey's northwestern quadrant where elevations are generally over200 (to 1800) feet. This "Upper Piedmont" subregion incorporates portions of the Appalachianand Highlands geological provinces. The "Lower Piedmont" subregion would encompass most ofcentral New Jersey, extending to the northeastern and southwestern portions of the State, with theFall Line intersecting it in a roughly axial fashion (Figure 1). The Lower Piedmont subregionwould thus include portions of the Piedmont and Coastal Plain geological provinces.

Within and adjacent to the Lower Piedmont ecoregion are large areas of substantially differentgeography or land use which should be considered as subregions. Foremost, this includes theurban/industrial areas of northeastern and (to a lesser degree) southwestern New Jersey, wherehuman activity has drastically altered the natural land and water configurations. Secondly, the "redshale" outcroppings and stream bottoms of the Raritan River watershed, adjacent to and north ofthe Fall Line (Figure 1), vividly contrast with the substrates of the surrounding regions. Thirdly,for the Middle Atlantic Coastal Plain ecoregion, the Pinelands and its associated border areasshould be delineated from the rest of the ecoregion (see Figure 1). The "Pinelands" subregion

would encompass that portion of the Middle Atlantic Coastal Plain ecoregion characterized bybrown (cedar) water streams, sandy soil and oak/pine forest. This subregion comprises the majorportion of the Middle Atlantic Coastal Plain ecoregion in New Jersey, and it is the largest of allour proposed, "subregions." An "Inner Coastal Plain" subregion could thus be defined as thearea(s) intermediate between the Pinelands and the Lower Piedmont subregions. The Inner CoastalPlain subregion would include that portion of the Coastal Plain, widest at the southwestern andnortheastern extremes, containing primarily farmland and hardwood forest (Figure 1).

Our design also roughly conforms with the major watershed (drainage-basin) boundaries (seeTable 1). The Upper Piedmont subregion, with swift flowing streams, encompasses the northernDelaware River tributaries south to about the Fall Line at Trenton. It also encompasses the upperPassaic/Hackensack and Raritan River drainage's (where most of their respective ecoregion sitesare located). The Lower Piedmont subregion encompasses the lower Passaic/Hackensack, Raritanand lower Delaware River drainages. The Assunpink Creek is unique in that its main branchoriginates in the Lower Piedmont and flows northwestward to the vicinity of the Fall Line,meeting some of its tributaries from the Upper Piedmont. Similarly, within the lower elevations,the Millstone River is the only major tributary to originate south of the Fall Line and flownorthward across it (to the Raritan River). A few of the lower Delaware tributaries, especially theRancocas Creek, originate in the adjacent Middle Atlantic Coastal Plain ecoregion but flowthrough the Lower Piedmont. The Pinelands subregion would include all of the Atlantic drainagebasin from the Manasquan River to lower Delaware Bay and the Maurice River drainage.

METHODS

General Study Design

From October 1989 to August 1991, potential ecoregion biological reference sites were surveyedin central and southern New Jersey. From August 1991 to July of 1993, the northern DelawareRiver watershed south to Camden, the Hackensack-Passaic and upper Raritan River drainages,were sampled for ecoregion sites in conjunction with the Department's Ambient BiomonitoringNetwork (AMNET). During the initial phase of the survey (8/90-7/91) 303 sites were visiblyscreened; from these, a total of 81 biological samples were collected from 45 selected sites. Basedon sample analysis, only sixteen of these sites proved to have a healthy biological condition andthus were accepted as ecoregion reference sites. During the second phase (8/91 - 7/93) about 345sites were visited and sampled; of these only 27 sites were selected for ecoregion status. Allecoregion sites were sampled subsequently three times to determine seasonal variation inmacroinvertebrate assemblages. Latitude and longitude were later determined using electronicsatellite Global Positioning Units.

When being considered for ecoregion biological reference site status, individual sites were visiblyscreened before sampling to see that the following physical criteria for habitat assessment (inPlafkin et al, 1989) were met:

1. good apparent water quality (i.e. clarity)2. good bank stability, with vegetation and streamside cover present3. no channel alteration4. no excessive siltation5. no suspected point source discharges upstream6. potential pollution from construction, urban or agricultural areas minimal

Accessibility of the site and the presence of a stream depth appropriate for wading were bothfactors considered during site selection.

Sample Collection and Analysis

For field and analytical methods, USEPA Rapid Bioassessment Protocols (following Plafkin et al.,1989) were employed. The protocols include both a qualitative and semi-quantitative assessmentof benthic macroinvertebrate populations. RBP(II) protocols have been adopted as standardprocedures by the BWM Biomonitoring Laboratory. While not intended to replace conventionalmethodologies, they have been developed expressly to assist planning and management effortssuch as screening, site ranking, prioritization and trend monitoring. They are especially usefulwhen doing biosurveys on a regional scale, of entire watersheds, and involving a large numberof sampling locations such as we are conducting.

Field Methods

Within the scope of RBPII protocols, our field methods (also described in NJDEP, 1992) weremodified as required by the physical attributes of typical sampling sites, and by our availablelaboratory resources. As opposed to sampling only the riffle/run habitat, our field collections weremade using the multi-habitat approach. This samples the various types of substrate (e.g., finesediment, gravel-rocks, woody debris, stream and bank vegetation, etc.) found at each site, thusminimizing substrate variation from station to station. Sampling several different locations at eachsite, a Surber net was used in very shallow streams (<2 feet deep) while, in deeper wadeablestreams, a kick net was used. In order to include a macroinvertebrate functional group (i.e.,shredders) not found in other substrates, a separate sample of course particulate matter (CPOM),primarily decomposing leaf litter, was collected by hand. In the field all samples from a particularsite were composited, sieved through #30 mesh and preserved with formalin to a 5-10 % finalconcentration.

Laboratory Methods

In the laboratory, subsamples of 100 individuals were taken by first evenly distributing thecomposited sample in a light colored gridded pan, then removing all organisms from randomly-selected grids until a total of 100 was obtained. The macroinvertebrates were identified to species(where possible) and counted using 7-30 x stereozoom and 40-400 x compound magnification.

Taxonomy

In the BWM Biomonitoring Laboratory, species level identification is considered standardprocedure. A comprehensive and current reference collection with taxonomic keys is maintained;an indexed list of species found in New Jersey (J. Kurtz, unpublished report) includes thefunctional feeding group, or niche, designations (see Merritt and Cummins, 1984) and pollutiontolerance classifications (from Hilsenhoff, 1982), for each species. Consultation with otherscientists in the field, when necessary, provides added assistance and confirmation. The presenceof "benchmark species," those that are considered pollution-intolerant or clean-water indicators,was a major factor in ecoregion site selection.

Data Analysis

The level of biological impairment (or lack of it), reflective of water or habitat quality, was alsoa major factor in ecoregion site selection. Biological impairment (most typically caused by organicenrichment) can be assessed using "biometrics" which measure different components ofcommunity structure, including population and functional parameters, and have different rangesof sensitivity to stress (Klemm et al., 1990). The use of more different metrics assures a morevalid assessment; the results (based on 100-organism subsamples) are integrated through commonscoring criteria, derived from an established comparable database, to give an overall numericalrating (see Appendix B). For RBP II protocols, scoring criteria have been adjusted and validatedfor family level taxonomy, with three final condition categories (non-impaired, moderately andseverely impaired). The biometrics we employ (listed below) are modified from Plafkin et al.

(1989) and follow Kurtenbach (1990):

1. Total Taxa or Taxa Richness (#families) - an index of community diversity; the #usually increases with increasing water or habitat quality.

2. Percent Contribution of the Dominant Family (to the total # families) - domination byrelatively few species/families would indicate environmental stress.

3. EPT Families - the # families represented within the orders Ephemeroptera (mayflies),Plecoptera (stoneflies) and Trichoptera* (caddisflies), which are generally pollution-sensitive.

4. Percent EPT (to the total # families) - would increase with increasing water quality.

5. Hilsenhoff (Family) Biotic Index - tolerance values of 0-10 assigned to individualfamilies increase as water quality decreases; summarizes the overall (organic) pollutiontolerance of the entire benthic macroinvertebrate community with a single value.

The individual biometrics and respective scoring criteria (above) have been statistically validatedfor New Jersey by Kurtenbach (1990) based on data from 200 sites throughout the state; these areshown in the Appendix of the present report. Our results are computerized and tabulated usingMicrosoft BASIC software.

RESULTS AND DISCUSSION

Table 1 lists the ecoregion sites by major drainage system in general order north to south, east towest, with the Upper Delaware first and Atlantic Basin last. The correspondingecoregion/subregion is shown to the right of each numbered site. Site locations ecoregions andsubregions are delineated in Figure 1 with the USEPA ecoregions shown by solid lines. Of the 43sites found in the present survey, 23 (slightly more than half) are located north of the Fall Linein the zone of hard rock and faster-gradient streams; these are situated largely in the UpperPiedmont and the North Central Appalachian (ridge and valley) ecoregion at the state's northernend. The other twenty ecoregion sites lie in the flatter, more easily eroded soils south of the FallLine, which comprise more than half of the state's total area. Of these, about seventeen aresituated in the Middle Atlantic Coastal Plain ecoregion, which includes the Inner Coastal plainsubregion (Figure 1). The other few sites, intermediate between the Coastal Plain and UpperPiedmont, fall into the Lower Piedmont ecoregion; these are located in and near the farmlands ofsouth-central New Jersey. Detailed descriptions and data for each site are given in the Appendix.

Spatial Distribution of Reference Sites

Clustering of ecoregion reference sites was noted in several areas of New Jersey. These included,most prominently, sites #2 to #8 within the North Central Appalachian ecoregion. These sitesencompassed primarily the Big Flat Brook watershed in the northernmost corner, where elevationand gradient are greater than elsewhere in the state. A few other New Jersey streams had morethan one ecoregion site situated along their main stem. These included the Nishisakawick Creek,(sites #12 to 14) also in the Upper Delaware, and the Great Egg Harbor River (sites #38 to 41)in the Atlantic Coastal basin (Figure 1). In north central New Jersey (Upper Piedmont ecoregion)sites #18-23 were clustered in adjacent portions of the Upper Passaic and North Branch RaritanRiver watersheds. In the southwestern portion of the state, several sites (#26,#29-30, and #38)were situated in relative proximity along the ridgeline which separates Lower Delaware andAtlantic Coastal watersheds; similarly, sites #32 to 34, and #24, in south-central New Jersey weregrouped near the divide(s) between southern Raritan and Atlantic coastal tributaries. Statewide,many of the ecoregion reference sites (25 of 43) were located close to the headwaters of streams.All of the areas or watersheds mentioned above have been relatively undisturbed, at least in recenttimes, for various reasons (e.g. being on state-owned lands, marginal farmlands, wetland, orotherwise unsuited for development) which accounts in a large measure for their acceptability asreference sites.

Conversely, in several large portions of the State there appears to be a dearth of stream locationssuitable for the establishment of ecoregion biological reference sites. Primary among these, in theLower Piedmont ecoregion, are the highly impacted urban/industrial subregions of northeasternand southwestern N.J., and the "farm belt" which extends from central to southwestern NewJersey (Figure 1). In the central Pinelands, many of the stream segments, although minimallyimpacted, are not readily accessible. Also, the abundance of cedar and pine needles in somePinelands stream locations (e.g. site #27) may preclude the availability of suitable food sourcesthus creating some degree of natural impairment. In addition, coastal and tidelands regions havenot been included in the present survey, as RBP methodologies and criteria for these regions have

yet to be established.

Statewide, most of the ecoregion sites (#25 of 43) are situated on "first order" streams (see Hynes,1976), or near headwaters (Table 1). This is most obvious in southern New Jersey where sites aregrouped along the ridgeline separating the Atlantic coastal from the lower Delaware and southernRaritan drainages. Nine of the sites are on second order streams, seven or third order and two onfourth order streams (see Table 1). Inasmuch as the lower order sites tend to be farther removedfrom the influence of potential impact sources, more ecoregion sites are needed to serve asreferences on the higher order streams (those with a greater hierarchy of tributaries).

Rationale for Establishment of Reference Sites

A great majority of the ecoregion sites (#29 of 43) were selected primarily for having diversepopulations of clean-water or benchmark species, reflecting minimal biological impairment, inrelatively unimpacted areas (Table 1). Five of the sites (#16,24,25,26,32) had slight to moderatebiological impairment in very impacted watersheds, but they exhibited "remnant" populations ofseveral clean-water species; these were located largely in agricultural areas of the Lower Piedmontecoregion of south-central New Jersey. Significantly, site #35 (Toms River headwaters), in a lessimpacted area, exhibited the most diverse population of benchmark species in central and southernN.J. deciduous woodlands associated with the agricultural areas. Elsewhere in the Inner CoastalPlain ecoregion, three sites (#31,33,42) retained diverse benchmark populations within highlyimpacted areas. Three other sites (#9,27,30) showed various degrees of biological impairment,but each possessed some unique feature for its particular ecoregion (see Table 1). Virtually allecoregion sites had good bank stability with some degree of bank vegetation, and trees orstreamside cover/canopy.

Benchmark Species

The pollution-sensitive species are largely the immature (nymph) stages of aquatic insectsbelonging to the orders Plecoptera (stoneflies), Ephemeroptera (mayflies) and Trichoptera(caddisflies), with a few belonging to the Coleoptera (beetles). Based on these results alone, thestate could be separated arbitrarily into only two ecoregions with the Fall Line (Figure 1) as thedivision. Obvious habitat differences exist north to south of this line, and species compositionshows distinct similarities within each region.

A total of 152 benchmark species were found statewide. About 130 of these species were foundnorth of the Fall Line while, south of it, less than half that amount (about 60) were found.Individual station totals of almost 50 were found in the faster-gradient streams and more variedsubstrates to the north. Notably, three times as many ephemeropteran species were found northof the Fall Line as south of it while, for the other orders, the difference was not as great. Weattribute these differences in part to varied water quality and habitat requirements among theseparate taxa. In southern New Jersey, ecoregion reference sites in the vicinity of the Pine Barrensexhibited the greatest variety of benchmark species (up to 30+ in the Great Egg Harbor River),while those in agricultural areas had the fewest (3-10). A different species association (group ofspecies) was found to be characteristic for each ecoregion or each cluster of ecoregion sites.

However, similarities in species composition were apparent between adjacent areas of twoecoregions, or between sites in relative proximity to each other. The extensive data and summariesfor all sites are contained in the Appendix to this report.

NOTES

Reason for ecoregion site selection: a - minimal biological impairment, diverse population of clean-water species b - outlet of a lake with no obvious sources of pollution; slight to moderate impairment;

can be used to gauge other lakes in the region c - site/stream uniquely atypical of the surrounding region; slight impairment d - least impacted site in the Assunpink watershed; moderate impairment e - limited or remnant population of clean-water species near headwaters of a very

impacted watershed; moderately impaired f - situated in an unimpacted area of relative wilderness (cedar swamp); moderately-impacted status probably due to lack of food supply g - in a relatively remote area but showing some impact (moderate to severe impairment) from a distinct source, in this case cranberry bog operations; can be

compared to less impacted site(s) upstream h - diverse clean-water population in a highly impacted area; an important site from this

standpoint; slightly to moderately impaired i - great diversity and abundance of clean-water species in a relatively pristine area,

but with encroaching development; no impairment; this is a very important site and canbe used to gauge other ecoregion sites in central and southern NJ deciduous forestedareas

Stream order, or position of a stream in its heirarchy of tributaries (see Leopold et al, 1964, Fluvial Processes in Geomorphology): 1 (= first order) - no tributaries, usually closest to headwaters 2 (= second order) - with only first order streams as tributaries 3 (= third order) - only second and first order streams as tributaries 4 (= fourth order) - only third, second and first order streams as tributaries; the

highest order on which ecoregion sites were found in the present study
